I do not know what might happened friend I just got a message from the server saying the ip was different.

I tried everything .... the only browser that seems to connect to the specific site is the Opera !?! all other browsers from whatever machine can not view the site !!!????!!!! I realy do not know what to do or what it may be the problem ???

Might be because your ISP has barred connection to the sub-domain *.host22.com, a alot ISPs in some countries do it for whatever reason. I think Opera connects to the Web via a proxy (most likely outside of your ISPs restrictions) to compress the website giving you faster browsing by removing useless headers and making images smaller.

My site on host222 is unreachable by me as well and my provider is comcast. Others are able to get to my site. I have switch my DNS but still no lock. I tried an older version of Opera but it cannot find my site.

There appears to be some sort of world-wide trend at the moment, where ISPs are blocking access to either 000webhost sub-domains or the server IP addresses. All this is thanks to the people that want to abuse a free service, using it re-distribute copyrighted protected material or allow access to illegal / illicit material, if I was 000webhost... I would pull all sub-domains before the reputation of an excellent service is destroyed by these people.
I was going to offer free sub-domain hosting via my webhosting service, but quickly decided against it when I saw what was going on at 000webhost.
